WMO

Country specific findings and challenges

Mauritius (Mr. Dhurmea Ram Kumar)

Challenges

Mauritius is on the periphery for the FOV of MSG at 0 degree

Preparation for new generation satellites

Product (Utilization and Interpretation)

Findings

Using products from Meteosat 7 (IODC); INSAT- 3D data are not

available; and relatively poor products from FY-2D

Need more training on monitoring convective activity in a marine

environment; this includes training on scatterometry, images

interpretation (RGB products are critical), manipulating of raw data

to derive products.

EUMETSAT and COMET provide well tailored training materials

Tried out SATURN website and found it to be good and more

information need to be provided

10th African User Forum recommendations

Recommendation #3: Improving user awareness of

satellite data and products

Data providers take further steps to communicate the existing

satellite products.

Recommendation #9: user preparation for new satellite

generations

EUMETSAT takes into account the african user community in its

planning to prepare users for the meteosat third generation

and for the EPS second generation programmes

Part of the objectives of the WMO 2012 Survey was to

identify areas for improvement and remedial action

Assistance is provided through:

1. WMO Online Resources (OSCAR, PAG, SATURN)

2. WMO-CGMS VLab, EUMETSAT and COMET training activities and

resources in support of RA I

3. CGMS-42 recommendations and actions (re Indian Ocean Data

Coverage)

The next slides explain briefly the WMO online resources and

how they are used to respond to the stated challenges

11

(1) Product Access Guide (PAG)

Goal & Objectives

• Web-based WMO resource

• In support of the WMO Information System

• Developed to address insufficient user awareness of

satellite products (WMO Survey, 2012)

• Facilitates access to quality controlled satellite data and

products

• Developed to enhance visibility of satellite products and

related information

• Providers of satellite data retain full ownership and

responsibility for their products

12

(1) Product Access Guide (PAG)

Implementation

• Links to stable URLs of satellite product collections,

expert groups, training material

• Products must be sufficiently described to meet user

demand for information (metadata criteria)

• Structured by geophysical domain, tags

13

(1) Product Access Guide (PAG)

Acceptance into PAG is based on the following Metadata

Criteria:

With the aim to satisfy users` needs for documentation

and to harmonized online product metadata used by

providers

14

Point of contact Applicability domain

Product identifier Geographical region

Providing organization Resolution

Data source Update frequency

Access information Quality indication /

documentation

(1) Product Access Guide (PAG)

1. Hierarchical/Simple Search: select by clicking on the domain

2. Advanced Search: based on combination of tags:Domain, theme, geographic

regional, organization providing and type of content.

3. Highlighted themes: based on themes such as Tropical meteorology, water,

health, disaster

CGMS-42 : Considerations

CGMS-42 WGIII actions: Indian Ocean Data Coverage (IODC)

A42.01: WMO to dialogue with Indian Ocean satellite operators and clarify

which data are essential in the sense of Resolution 40, in view of the

meteorological requirements in the region.

A42.08: ISRO and EUMETSAT to report at CGMS-43 on their discussions on

data dissemination collaboration for SCATSAT data.

A42.03 : WMO to consider sending a request to CMA for moving an FY-2

spacecraft over the Indian Ocean after successful launch and commissioning

of FY-2G.

A42.02 : EUMETSAT and ISRO will address the technical issues to

accommodate high-resolution half-hourly data from INSAT-3D on

dissemination means.

(3) SATURN - General motivation and objective

SATellite User Readiness Navigator Portal (SATURN)

The 2015-2020 generation of meteorological satellites provides: unprecedented capabilities for key meteorological applications such as nowcasting, as well as challenges for both satellite operators and users: Higher sampling rate, higher spatial resolution, more spectral channels

Expected to lead to more accurate and timely forecasts, and improved application support

Data rates increase drastically, by factors of 10-100

CGMS and WMO Space Programme developed SATURN to allow Members exploit the potential operational and socio-economic benefits of using next-generation satellites

Provides information on new generation of (initially) geostationary meteorological satellites: Himawari-8 (JMA), FY-4 (CMA), GOES-R (NOAA),GEO-KOMPSAT-2 (KMA),

Elektro-L N2 (ROSHYDROMET), MTG (EUMETSAT)
